Dear John
I am writing to you is want to recommend a movie where shows an Chinese assassin in Qin dying.The movie’s name is hero,you may be confuse.why an assassin is a hero,the reason of this phenomenon is that assassins have power,but they do not use it unlimited,because they know,with great power comes great responsibility.
In this movie,you would know a truth that a greet knight,for the country and for the people,it is the essence of the Chinese Xia culture.The chief actor of this movie is acted by Li Jet ,a famous actor in China,because he has kung fu ,so the movie’s content is splendid.I strongly recommend you to watch this movie.
Wish you enjoy the movie,look forward to your reply.
Your sincerely
Li Ming
